I have a multi-part form (like the wizard example in the docs) which travels from page to page using "Next" and "Previous" buttons.

Let's say I am on page1 and click next to go to page2. When page2 is loaded the URL bar says page1. If I go back to page1 with the Previous button or onwards to page3 with the Next button, then it says page2 in the URL.

I would like the correct URL to be displayed with the correct page.

Here is a snippet of VF markup from one of the pages:

<apex:page showHeader="false" controller="studentApplicationController" >
  <apex:includeScript value="{!$Resource.jquery}" />
  <apex:includeScript value="{!$Resource.js_utils}" />
  <style type="text/css">
      .required {color:#F00;}
  </style>
  <apex:sectionHeader title="Aish Hatorah Application - All information in this application is strictly confidental" subtitle="Page 6 of 7"/>
  <apex:form >
      <apex:pageBlock title="" mode="edit" id="pageblock">
          <apex:pageMessages />
         <apex:pageBlockButtons >
             <apex:commandButton action="{!page5}" value="Previous"/>
             <apex:commandButton action="{!page7}" value="Next" onclick="return validatePage('{!$Component.pageblock}')"/>
             <apex:commandButton action="{!cancel}" value="Cancel" 
                              onclick="return confirmCancel()" immediate="true"/>

         </apex:pageBlockButtons>

Here is the controller snippet for page redirection:

    public PageReference page6() {
      return Page.StudentApplicationPage6;
    }

    public PageReference page7() {
      return Page.StudentApplicationPage7;
    }

    public PageReference confirmPage() {
      return Page.StudentApplicationSubmitConfirmPage;
    }

thanks for any suggestions
